Biona Olive Oil: An Honest Review of the Organic Range
If you have searched for Biona olive oil, you have probably already seen the bottles — on Ocado, in a wholefood shop, or on Biona's own web shop — and found plenty of listings but very little plain explanation. So on 3 October 2026 we read Biona's own product pages and the main UK retailer listings, and set out what each states. Biona is a British organic food brand that has sold organic groceries for more than thirty years, and olive oil is one staple among hundreds. This is an honest review of the range: who makes it, what each bottle is, where the olives come from, what the organic certification covers, and what the labels leave unsaid.

The Short Answer
- Biona is a UK organic food brand founded in 1992 by Noel McDonald and Donata Berger; its olive oils are sold through biona.co.uk and UK retailers such as Ocado.
- On 3 October 2026, biona.co.uk listed three Biona Organic extra virgin olive oils — 500ml, 750ml and a 1-litre Italian bottle — plus a Greek 500ml bottle and a Greek oil from its sister brand Raw.
- Every Biona Organic bottle we checked lists a single ingredient: extra virgin olive oil, marked as a certified organic ingredient.
- Ocado's listings name the Organic Food Federation as the certifying body for the 500ml and 1-litre Italian bottles — a genuine, formal organic certification.
- Biona's own pages describe the 500ml and 750ml oils as made from "organically grown Mediterranean olives" and do not name a country, a cultivar, a harvest date or any lab figures.
- Sidr & Stone makes a different kind of oil: one single-estate, rain-fed extra virgin from our own farm outside Marrakech, organically grown but not yet certified organic.
Who Makes Biona Olive Oil
Biona is the organic food brand of a London-born business. According to the brand profile published by the northern supermarket Booths, Noel McDonald opened Windmill Wholefoods in Fulham in the 1970s, and in 1992 he and Donata Berger founded Biona — the name joins "bio", the word for organic in many languages, with "na" for nature. Biona's own home page says the company has spent "the past 30 plus years" working to make organic food more accessible.
The company behind the brand trades as Windmill Organics Ltd, and Ocado's olive oil listings give the manufacturer as Biona, with addresses in Kingston upon Thames and in Haulerwijk in the Netherlands. In other words, Biona is a brand owner and importer rather than a grower: it sources certified organic oil from Mediterranean producers and sells it under its own label, alongside tinned tomatoes, nut butters, rye breads and much else. That is a common, legitimate model — and a different one from a single estate pressing its own trees.
The Biona Olive Oil Range, Bottle by Bottle
Biona's web shop lists more olive products than oils — olives in brine, pâtés, a mayonnaise — so here is the oil range on its own, as each source states it on 3 October 2026:
| Oil | Size | Origin, as stated | How it is described | Organic |
|---|---|---|---|---|
| Biona Organic Extra Virgin Olive Oil | 500ml | Biona's site: "organically grown Mediterranean olives". Ocado: Italy | Cold-pressed; Ocado's listing calls it "light, nutty" | Certified organic ingredient; Ocado names the Organic Food Federation |
| Biona Organic Extra Virgin Olive Oil | 750ml | Biona's site: "organically grown Mediterranean olives" | Cold-pressed; "rich and fruity", for marinating, dipping and drizzling | Certified organic ingredient |
| Biona Organic Italian Extra Virgin Olive Oil | 1 litre | Italy | "The finest organic olives are carefully selected and cold pressed"; Ocado adds "100% Italian" and "unrefined" | Certified organic ingredient; Ocado names the Organic Food Federation |
| Greek Extra Virgin Olive Oil (Biona) | 500ml | Greece | No product description on the page when we looked | Not stated on the page |
| Raw Greek Extra Virgin Olive Oil (sister brand Raw) | 500ml | Greece | "Raw. Cold Extracted." | Not detailed on the page |
Two things stand out. The core Biona Organic oils are single-ingredient extra virgin, with nothing added. And only the 1-litre bottle names its country on Biona's own site; the 500ml and 750ml say "Mediterranean". Our guide to what "Italian" actually means on a bottle explains why that word matters.
The Organic Certification: Biona's Clearest Strength
Biona's ingredient line reads "Extra Virgin Olive Oil*", with the asterisk explained as "Certified Organic Ingredients". That is a formal claim, not a mood word. In the UK and EU the word "organic" on food is protected: it can only be used where the producer, processor and importer are inspected by an approved control body, and the label must carry that body's code.
Ocado's listings for the 500ml and 1-litre Italian bottles name that body as the Organic Food Federation, one of the UK's approved organic certifiers. We have not seen the physical label ourselves, so we report the certifier as the retailer states it; the code printed on your bottle is the final word.
This is a genuine strength and we will not downplay it. A certified organic oil has been audited by a third party, from grove to bottle, against a published standard. Our guide to what the organic label really means sets out what that certificate covers — and what it does not, such as freshness, flavour or polyphenol content.
"Mediterranean" and "Italian": Reading the Origin Line
Olive oil labels in the UK and EU must state origin. A single-country oil names that country; an oil blended from several countries says so, as a blend of EU oils, non-EU oils or both. "Mediterranean" on a product page is marketing copy rather than a regulated origin statement, so the origin line on the back label is what counts.
Here the sources do not fully agree. Biona's site says "Mediterranean" for the 500ml and 750ml; Ocado lists the 500ml with Italy as country of origin and calls it Italian; another retailer's listing titles the 750ml "EU Origin". The likeliest explanation is that sourcing, or listing copy, has changed over time. Our practical advice: read the origin on the bottle in your hand, and if it matters to you, choose the 1-litre Italian, which states its country plainly.
None of the Biona pages name an olive variety, an estate or a harvest date. That is normal for a brand-owner range — but it means you are buying the Biona name and the organic certificate, not a specific grove.
Three Fair Objections
"Certified organic beats 'organically grown'." On certification, yes. Biona's oil carries a formal organic certificate and ours does not yet. If an audited organic certificate is your first requirement, Biona meets it today and we do not.
"A big organic brand is more trustworthy than a small farm." Scale brings audits and consistency, which are real. A single estate offers a different kind of trust: one origin you can name. Our guide to choosing a quality olive oil explains how to weigh certificates, origin, dates and taste.
"You don't publish lab figures either." Correct. Neither Biona's pages nor ours show acidity or polyphenol results; our current batch has not yet been analysed by an independent laboratory. We will not imply a figure we do not have.
How to Choose Within the Biona Range
- For a named single country, choose the 1-litre Italian Extra Virgin — the only Biona Organic bottle whose own page names its origin.
- For a smaller bottle you will finish while fresh, the 500ml makes sense; once opened, olive oil is best used within a few months.
- Check the back label for the origin line and the organic control body's code.
- Look for a best-before date as far ahead as possible; a harvest date, where printed, is better still.
- Keep it in a cool, dark cupboard, as Ocado's listing advises, away from the hob.

Biona and Sidr & Stone, Side by Side
Biona is ahead of us on formal organic certification, on range and sizes, and on how easy it is to find on UK shelves. What we do is narrower, not better: one farm, one oil.
| What a buyer might check | Biona (own site and Ocado, 3 October 2026) | Sidr & Stone |
|---|---|---|
| Who grows the olives | Mediterranean producers; Biona sources and brands the oil | Our own family farm on the plains outside Marrakech |
| Origin named | Italy for the 1-litre; "Mediterranean" on the 500ml and 750ml pages | Morocco — one named estate, unblended |
| Organic status | Certified organic; Organic Food Federation per Ocado | Organically grown; not yet certified, certification in progress |
| Extraction | Cold-pressed, as stated | Cold-pressed within hours of harvest |
| Filtration | Not stated | Unfiltered; may show natural sediment |
| Published lab figures | None on the pages we read | Not yet — current batch not yet analysed |
| Sizes | 500ml, 750ml and 1 litre | 500ml only |
Why Sidr & Stone
Biona shows what a long-standing organic brand does well: a formal certificate, a clean single-ingredient label and an oil that is easy to buy. Sidr & Stone's olive oil starts from a different place — one farm, named — and everything below describes how it is grown and made, not a certificate or a laboratory figure, because we do not hold either yet.
- Sidr & Stone's extra virgin olive oil comes from a single estate — our own family-owned farm near Marrakech, Morocco — and we control every step from tree to bottle, with no blending across origins.
- The Sidr & Stone grove is rain-fed, with no irrigation; the trees take what the season gives.
- Sidr & Stone's olives are organically grown, with no synthetic fertilisers, pesticides or herbicides (not yet certified; certification is in progress).
- Each Sidr & Stone release is a small, limited single-harvest batch; once it is gone, it is gone until the next harvest.
- Sidr & Stone's oil is cold-pressed within hours of harvest to protect flavour, aroma and polyphenols.
- It is unfiltered extra virgin, minimally processed, and may show a little natural sediment — normal in an unfiltered oil.
- It is 100% natural — a single ingredient, olive oil, with no additives — in a 500ml dark glass bottle that protects it from light.
- Sidr & Stone gives 10% of profits to charity, with fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is a better olive oil than Biona — a certified organic, single-ingredient extra virgin from a brand with three decades in organic food is a sound choice. What we will say is that ours is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest, and that the harvest details for the current batch are on the product page.

Frequently Asked Questions
Is Biona olive oil good?
It is a certified organic, single-ingredient, cold-pressed extra virgin olive oil from an established UK organic brand. Its own pages do not name a cultivar, harvest date or lab figures, so judge each bottle by its label and taste.
Is Biona olive oil certified organic?
Yes. Biona lists the oil as a certified organic ingredient, and Ocado names the Organic Food Federation as the certifying body for the 500ml and 1-litre Italian bottles. The control-body code is printed on the label.
Where does Biona olive oil come from?
The 1-litre bottle is Italian. Biona's site describes the 500ml and 750ml as made from "organically grown Mediterranean olives", while Ocado lists the 500ml as Italian — check the origin line on your bottle.
Is Biona olive oil cold-pressed?
Biona describes its extra virgin oils as cold-pressed, and its sister brand Raw describes its Greek oil as "cold extracted". Our guide to what cold-pressed actually means explains both terms.
How does Biona compare with Sidr & Stone?
Biona offers certified organic oils in three sizes, sourced from Mediterranean producers. Sidr & Stone makes one single-estate, rain-fed, unfiltered extra virgin from our own farm outside Marrakech, organically grown but not yet certified.
Which Biona olive oil should I buy?
For a named single origin, the 1-litre Italian Extra Virgin. For freshness in a small household, the 500ml. Either way, check the best-before date and keep the bottle somewhere cool and dark.
Where can I buy Biona, and where can I buy Sidr & Stone?
Biona sells through its own UK web shop and retailers such as Ocado. Sidr & Stone's oil is sold directly from our product page, with fulfilment in the UK, EU, and US.
Is olive oil a medicine?
No. Olive oil is a food, not a medicine. It has a long traditional history — including being honoured in the Prophetic Sunnah — and a substantial body of modern research, particularly around polyphenols, cardiovascular health, and the Mediterranean diet pattern. It can be a worthwhile part of a healthy routine, but it does not cure diseases and is not a substitute for medical care. Be cautious of any olive oil marketed with specific disease-cure claims.
Final Thoughts
Biona does the important basics well: a certified organic oil, a one-ingredient label, cold-pressing as stated, and wide availability from a brand that has worked in organic food since 1992. If an audited organic certificate is what you need in your basket today, Biona provides it, and we are glad to say so.
What the range does not offer is a story you can trace to one place. "Mediterranean" covers a lot of coastline, and none of the pages name a variety, estate or harvest date. That is a choice, not a fault — but it is worth knowing before you buy.
Our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml) is single-estate, rain-fed and cold-pressed within hours of harvest, available as a limited single-harvest batch with fulfilment in the UK, EU, and US.
Our extra virgin olive oil is grown organically on our own single-estate farm on the plains outside Marrakech: we control every step from tree to bottle, and no synthetic pesticides, herbicides or fertilisers are used. It is not yet certified organic — certification is in progress, and we will publish it as soon as it comes through.
